Calculate the LCM of 390,124,635,635

Given numbers are 390,124,635,635

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 390,124,635,635 is 3070860.

Find LCM of 390,124,635,635 with Prime Factorization


2 390, 124, 635, 635
5 195, 62, 635, 635
127 39, 62, 127, 127
39, 62, 1, 1

Multiply the prime numbers at the bottom and the left side.

2 x 5 x 127 x 39 x 62 x 1 x 1 = 3070860

Therefore, the lowest common multiple of 390,124,635,635 is 3070860.

LCM Formula to Find Lowest Common Multiple of 390,124,635,635

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

390 x 124 x 635 x 635 = 19499961000

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390

124 : 1, 2, 4, 31, 62, 124

635 : 1, 5, 127, 635

635 : 1, 5, 127, 635

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 390,124,635,635, is 1.

Now, the common factors can be found like this.

390:2x 3x 5x 13

124:2x 2x 31

635:5x 127

635:5x 127

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 5x 5x 127 = 6350

Therefore, the value for common factors is 6350.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 19499961000/(1x6350)

LCM = 19499961000/6350

LCM = 3070860

Thus, we can understand that the LCM of 390,124,635,635 is 3070860.
